Be it known that we, lieu; sud Ovnu. Bnnra, both cub cuts 0! the King ofEnglnnd, residing ot ndon in England, have invented eel-tom new enduseful Improvements in Detaehalgle Roms for Wheels, of which thefollowing 15 a specification.

This invention relates to detachable runs for wheels which may beremoved from and applied to the folly of the wheel byan axial movementeven though the rim or' fell is considerably out of truth. The rim is tivided tronevcrselv into separable sections that are moved 'hoclily away[rum or toward each other for the purpose of expending or contractingthe rim when it is to be applied to or removed irom the folly. This runprefornhly' comm-gees four sogmeets each of which may applied separatelyto the tire. When in position the -se ments are fore-ed apertMiddflhtlllltil hi this expended position by means of keys 0 rating atthe junctions of the ends of t e rim segments. The expanded run is thenapplied to the folly of the wheel and afterward allowed to contract uponthe. folly by removing the keys.

'1 his invention refers more particularly to 80 on improved method oisecuring the tire to 'thoriin and the rim to the wheel, and also onimproved mechanism for separating the meeting ends of the sections.

According to this invention, in detachable 86 rims having separablesections the tire is socured to the run and the rim to the wheel orhuh-member by n bolt passing through the folly and engegm f n securitypad inenle the tire. Or the oltme be integral with the security pad anda opted to re eeive a nut to secure it in place.

In order tosefinretothe sections a. to gle plate is, pivots y connectedto the exert arm of n' lever the toggle plate and the vacant ends of twosection so t et-movement-ofthe lover separstoe 'the sections. One and atthe toggle plnti-ondwho iulemm of the lever are provided with pine whichput ,throngh else, 50, formed inthe adjacent ends of the two sectionaqnda similar device is applied to the other side of the rim and engageswith the some p The Jenn Wnunn invention will now be de'ecribod withreferfinco to the accompanying drawings, in w m:

The first art of our invention will be deserihed with reference to Figs.1 to 4. The run, according to this particular eonstruetion comprisesfour segments whereof one is indicated at A. Sup rting blocks aresecured at each end of one segment and a further snF ort is secured inthe center of the some. no central support is provided with n lnfnrcntedextension so that when the section in in position on the folly thisextension will engage a drivin block secured to the folly of tho whee..At one end of the section a block B is secured 90 either by menus oirivets 0', as illustrated, or in any other suitable manner, and extendsheyond the end of the section, as illustrated m Fig. 2. The block isprovided with a channel 1) extending back more. than be]! way into thebody thereof. At each side 01 the channel it maybe provided with two,raised portions D and the sides have formed on thorn flanges l) which,when the rim is m ltion on tho-wheel, reject over the thereof andprevent sule movement of the rim. The other end of the rim-section inprovided with a. block 0 the face oi which is set back some distancefrom the edge of the rim-section and a distance greater than theprojection of the block B be end the Edi: of the adjacent rim-section.he s nee E tween the face of the-blocks O and it protecting the innertube.

armed in the blocks B and 0 respectively the security such that a llathe may be inserted easily between them. Tic block 0 is provided with twolien cs 0' C which also lap over the ed a of tie wheel when the rim isjnplace at the llangc C is clongatcdnml is provided with a slot C. Thesecurity pads rim is ex lazanded by 'nserting a llat key in the space apro ection from the key resting in! the channel C which acts asa'bearing for the key. .The key is then turned through 00 ancl'thusseparates the sections. The expanded rim and tire are then.lifbed ontoil] wheel and the rim is contracted by the wit drawn] of the keys. Thesecurity bolt's' afe then passhd through holcs made fori that. purposein the telly of the wheel on are screwed into the security pads. Tlpedepads serve the triple purpose 0 (1)- loding thc'tirouj inst creeping;(2) securing the rim to t to wheel by conjunction with the securitybolts, and (3) closing the space left between the rim-sections, therebyHoles F are for-the insertion of a tool for prying the last section intoposition on the tire. It will be seen that in this construction thesecurity. pads are placed over the junction of the rin1-scctions, whilethe space for the insertion of the expanding key Is located to one sidethereof.

In a modified construction the boss on the security pa is eliminated andonly the thickness of the bod of the pad is tapped to receive the bolt.t would not then necessitate the space for the insertion of the keybeing provided to one side of the security bolt", All that would than benecessa to expand the wheel would be to with raw bolt and insert the keyin the space formed immediately under the center l of thesccurit pad andat the junction of the blocks as raving no boss,

the pad would not cxten into the block and' a free pas- .sagc for thekey would be provided. One

exam le of such a construction is shown in Fi in which the pad isrovidcd with a hultit I integral therewith, he bolt bc1ng provided with'a screw-threaded portion to reeeit e a hollow bolt m at the and remotefrom the pad. In a construction of this character, when the bolt isremoved, the he can be inserted in tho, space between the en s of theegmefits.

The second part of our invention is illustrated in Fi's. 5 to 12. Inthis case the meeting ends of the sections have a portion rll. away, andblocks G and ii are secured in the spam-s thus formed. They are provded, as before with spaces for the inscr' tlhtl ol lho security pads andone of them Inn, plnjtf 'llulh-i ll ivhich engage in the slots G fornmlfor that illl'pn'stt. The blocks G have portions ll which overlap theend of the riot and, when in the contracted position on the wheel,overlap the end of the adjacent rim-section. The blocks G and H haveholes G and II respectively formed in them. The projections G are alsoprovided with holes (i and the projections 11' on the block l- I havesemi-circular portions I'i cut awn The tool for separating the meetingon s of the sections is composed as follows:-.\ toggle pinto J ispivoted at J to the short arm of the icvcr J. The other end of thetoggle plate J has a boss formed on it and secured in the boss andproject-in from it is a pm K. The fulcrum oint o the lever J is alson'ovidcd with a as; having a pin K secure thereto.

To separate the sections, the pins K K urc'inscrtcd in the holes Gr H asillustrated in Fig. 10, so that the pro ect from the rim on the oppositeside. -A similar tool (having holes instead of )illS which engage thepins K it) is a iplic to the )ins h. K on the other side oi the rim. '10 two le- \tl's are then sin'mltaneonsly turned in the direction of thearrow until in the position illustrated in Fig. 11. By this means therinrscctions are separated, as shown in Fig. 11, the semi-circularportions l-l registering with the holes G, so that when a pin isinsertcd in the holes, the rim-sections are locked in their separatedposition and the lever can thereafter be removed. In order to contractthe rim the lever is again applied to it as before described pressedinto the expanded position when the locking pin can be withdrawn and therim allowed to close together. The same oxpundi'n tool can also be usedfor the purpose of app yin r the last section of the rim to the tire andetaching the first section. For the latter operation the tool would beused in a. reversed position.

Security pads are inserted in the tire so that the bosses thereon restin the spaces formed for that nrpose in the rim block. Extensions to theoases of each sccurit pad are preferably formed on o posits si es ofeach screw threaded hole w nch is engpged by a security bolt. When thetire is 0 wheel and is in a deflated condition these extensions orient Lprevent the security pad from falling into t a tire by engaging with theled on (1 11 formed for that purpose in the en 8 of the rim-sections.

It is within this invention to modifiy the details of construction,rovided alwa s that they'are kept within is e spirit of he invention. I
